I have just read 4 hours worth of info and tried several things all to no avail. It's this business again:
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync ...
I'm using the FTDI basic with an Arduino Pro mini. Brand new.
I actually bought a second one of each just in case I had torched the first pair. Same sad situation. However:
-
I checked the connections and voltages.
-
All six pins on both headers are used between the boards.
-
The Arduino board has never been connected to anything but the FTDI basic (since I received it new).
-
I can see on an oscillocope that the reset is asserted, pin 29 of the Atmel (only once per download attempt, not once per stk500_getsync() attempt).
-
Nonetheless, I've got a blister from hitting the reset button in a series of boring and
unproductive trials. -
I can stop what I'm doing and program my Duemilanove robot with the same IDE, Genuino 1.8.3. The IDE and serial connection all work.
-
The Serial Monitor echoes if I connect the FTDI in loopback.
-
I see no activity on the Serial Monitor during download attempts (I don't know if I should expect to)
-
I even bought the recommended 3' USB cable with the second pair of parts.
-
The red LED for power is on.
-
On "programming" the green LED on the board blinks once, then makes one lame blink and nothing.
-
The FTDI voltage is unchanged from the factory 5v setting.
-
I have not yet heard back from Sparkfun if those boards come with a bootloader pre-programmed.
-
I even lost my mind and swapped the TX and RX lines in case the board was mislabelled.
-
I have some pictures, attached.
What am I missing here? I want to go back to etch tanks and EEPROM burners and wire-wrapping.
Any help appreciated.
